Investigation + design only (no client/backend/binary changes, no live Store experiment). Reconfirmed CardsDLL_Win64_retail.dll (4706a881.., unpacked) against a freshly rebuilt Ghidra project on .105; FIFA17.exe (29c31cef..) is Denuvo-packed so the Scaleform decision is unreadable. PART II added to docs/plans/FIFA17_EMPTY_MYPACKS_CLIENT_FIX.md: - Native category path traced: FUN_18007dab0 (store render, RVA 0x7dab0) reads screen+0x290; My Packs funnels through FUN_1800147f0 (0x147f0) -> FUN_180014420 (0x14420, NULL on ordinal miss) -> crash MOV [RDX+0x8] at 0x14882 ([NULL+0x48]), matching the Exp-B minidump. Tab->ordinal map FUN_180014580 (0=mypacks..5=special); category 0 = list-all (Browse). - Unopened-pack count is a data-manager singleton (vtbl[0x4d8] get / [0x4e0] set), reachable from the store resolver. - Vehicle: existing openfut-hook -> version.dll proxy (already deployed); reuse ssl_patch signature-scan + connect_hook inline detour. No new loader. - Preferred strategy A: entry-hook FUN_18007dab0; when the requested category is My Packs and unopened count==0, force screen+0x290=0 (Browse). Removes crash + fake 65534 tile + dialog + nav gate; count>0 untouched. - Ranked B (resolver NULL fallback, higher risk) and C (null-guard, crash-only). - Build guard: module gate + SHA/PE + signature scan; unknown build -> no patch, backend sentinel remains fallback. - First experiment design (needs a later, separately-authorized backend empty-no-sentinel test mode) + client rollback (config flag / dll swap). - Keep backend 65534 sentinel deployed until strategy A is verified. Describes the FIFA 17 client/data model only; not OpenFUT Core assumptions.
OpenFUT
Offline Ultimate Team — like SPT, but for FIFA 23.
OpenFUT replaces EA's retired FUT servers with a fully offline, single-player backend. You own FIFA 23 legitimately. You just want to keep playing after EA shut down the servers.

SQLite database
Core is game-independent. It speaks a clean REST API and knows nothing about FIFA 23 internals.
Bridge is FIFA-specific. It speaks FIFA 23's wire protocol and translates it into Core API calls. Bridge is where all reverse engineering work happens.

Running
# Start the offline backend
cd openfut-core
cargo run
# Start the proxy (for traffic capture / FIFA integration)
cd openfut-bridge
cargo run
Core listens on http://127.0.0.1:8080 by default.
Bridge listens on http://127.0.0.1:8443 by default.
Design Principles
- Offline-first. No EA account required. No internet connection needed.
- Single-player only. This is not a multiplayer server emulator.
- Data-driven. All cards, packs, SBCs, and objectives are JSON files. Everything is moddable.
- Clean architecture. Core has zero knowledge of FIFA 23. Bridge has zero game logic.
- No copyrighted assets. No real player images, no EA trademarks in data files.
